Share. By Regina Bailey. Definition: Mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. Chromatin is located in the nucleus of a cell. During prophase of mitosis, chromatin fibers become coiled into chromosomes with each chromosome having two chromatids joined at a centromere.
Chromatin vs Chromatid. The most important structures in the cell during division are the chromosomes which contain DNA. This is because they are responsible for the transmission of the hereditary information from one generation to the next.uring the interphase of the cell cycle, chromosomes are not visible because they appear as thin, long thread like structures called chromatin. Chromatin is long, thread like structures. These are made up of DNA and histone proteins.
